cannabis-science
Cannabis science is the multidisciplinary study of Cannabis and hemp plants, encompassing their genetics, biochemistry, and cultivation. This field matters for plant science because it deepens understanding of secondary metabolite production, particularly cannabinoids and terpenes, and reveals how genetic and environmental factors shape plant chemistry and growth. Insights from this research also inform breeding strategies aimed at improving yield, potency, and disease resistance in these economically significant crops.

Researchers mapped the gene networks that help hemp plants cope with low phosphorus in soil, finding distinct organ-specific responses in leaves and roots, and identifying a key gene (SPX3) that coordinates how the plant redirects resources toward reproduction when nutrients run short.
WGCNA identified 12 co-expression modules across hemp organs; 2 modules (leaf- and root-specific) were strongly correlated with phosphorus status and overlapped significantly with genes selected during Cannabis domestication.
SPX DOMAIN GENE3 (SPX3) was identified as a central hub gene in leaf tissue coordinating the shoot phosphate starvation response and prioritization of resources toward reproductive organs.
Strigolactone hormones and transcription factors from the SCARECROW-LIKE (SCL) family drive root system architecture remodeling under phosphate deficiency, revealing a hormone-mediated tolerance mechanism in hemp.
